The Pasco Mini Launcher (ME-6825B) has an optional accessory bracket, designed to all students to attach Pasco photogates to the end of the launcher. This accessory bracket is designed to fit only Pasco photogates.

If you have access to a 3D printer, you can print a bracket that attaches to the accessory bracket to allow students to use Photogate (VPG-BTD) instead. Printed in brown filament in the photos below, the bracket requires M3x20 bolts with nuts to attach the adapter to the Pasco photogate mounting bracket, and 1/4″x20 bolts with nuts to attach the photogates to the printed bracket.

You can download a STL file for the adapter here:
